About Capixyl
A patented hair-complex ingredient pairing a biotin peptide with a tetrapeptide—common in scalp serums marketed for thinning hair.
Capixyl combines Biotinoyl Tripeptide-1 (sometimes listed separately) with Acetyl Tetrapeptide-3 in a glycol base. Brands position it to support the appearance of denser, healthier-looking hair at the follicle level. It is a cosmetic active, not a drug—results are gradual and vary by person.
